Top of the line AUDAX HM170Z0 Woofer, 6.5s, 8 Ohms, quality made and designed in France, Cast Frame, excellent quality and performance. Open Box, New, Always inside climate controlled non smoking environment, Top Line, Ex Quality, France. The shipping cost includes safe packing, insurance, prompt shipping and tracking number. Buy with confidence, see my feedback. Good listening, SonnY :) See the impressive specs and description below HD-A represents a true breakthrought in loudspeaker cone technology, surpassing all conventional materials being used today. Through an extraordinary combination of newly developed materials and processes. Audax has created an innovative composite membrane whose properties are very close to ideal for making loudspeaker diaphragms. Ultra light, extremely rigid and maximized internal damping. This no-compromise cone ise based on a totally controlled matric of acrylic polymer gel in which an optimized proportion of Carbon and Kevlar fibers are embedded. An exclusive, proprietary process acts to perfectly align the fibers along the polymer chain. The procedure allows total control over the contour and weight of the cone, while making it possible to vary the thickness of the membrane along the profile. This 6 1/2 bass-midrange driver was developped for top range, no-compromise high end 2 or 3-way systems. It features a die cast Zamack chassis with unobstructed venting for enhanced transient response and a non resonant phase plug for high and frequency equalization. High power handling results from the flat, edgewound copper coil mounted onto a fiberglass reinforced Kpaton voice coil former. Unequaled definition is achieved over a wide spectrum of frequencies and dynamic ranges while retaining a neutral tonal balance with precise and detailed imaging.
